Paraganglioma
Leczenie

Paraganglioma to rzadki nowotwór wywodzący się z komórek chromochłonnych, wymagający wielodyscyplinarnego podejścia terapeutycznego. Podstawą leczenia jest chirurgiczne usunięcie guza, z wyborem techniki zależnym od lokalizacji i wielkości zmiany (np. laparoskopia dla guzów nadnerczy ≤6 cm, otwarta adrenalektomia dla guzów >6 cm). W przypadku guzów wydzielających katecholaminy konieczne jest przygotowanie farmakologiczne z zastosowaniem alfa-blokerów (fenoksybenzamina 10 mg 2-3x/d, doksazosyna, prazosyna) rozpoczęte co najmniej 7-14 dni przed operacją, a następnie beta-blokerów, aby zapobiec powikłaniom sercowo-naczyniowym. W leczeniu przerzutowym stosuje się terapie radioizotopowe (np. [131I]MIBG z odpowiedzią częściową u 27% pacjentów i stabilizacją u 52%), PRRT ([177Lu]Lu-DOTATATE wykazujące dłuższy czas przeżycia wolnego od progresji do 38,5 miesięcy) oraz chemioterapię (cisplatyna, winblastyna, dakarbazyna). Radioterapia frakcjonowana i stereotaktyczna stanowi opcję w przypadku nieoperacyjnych guzów lub nawrotów.

Leczenie paraganglioma – wprowadzenie

Paraganglioma to rzadki nowotwór wywodzący się z komórek chromochłonnych, który może pojawiać się w różnych lokalizacjach organizmu. Leczenie paraganglioma wymaga podejścia wielodyscyplinarnego i jest uzależnione od kilku czynników klinicznych. Do najważniejszych należą: lokalizacja guza, czy jest on złośliwy i przerzutowy, czy wydziela nadmiar hormonów (katecholamin) powodujących objawy oraz ogólny stan zdrowia pacjenta12.

Główną formą leczenia paraganglioma jest zabieg chirurgiczny, który w przypadku wczesnego wykrycia guza pozwala na skuteczne leczenie w większości przypadków. Jednak gdy guz nie może być usunięty chirurgicznie lub występują przerzuty, dostępne są inne metody terapeutyczne, które będą szczegółowo omówione w dalszej części artykułu34.

Przygotowanie farmakologiczne przed leczeniem paraganglioma

W przypadku paraganglioma wydzielających katecholaminy, konieczne jest odpowiednie przygotowanie pacjenta przed jakimkolwiek leczeniem, zwłaszcza przed zabiegiem chirurgicznym. Niekontrolowane wydzielanie katecholamin podczas operacji może prowadzić do poważnych powikłań sercowo-naczyniowych56.

Blokada alfa i beta-adrenergiczna

Przygotowanie farmakologiczne obejmuje przede wszystkim zastosowanie leków blokujących receptory alfa-adrenergiczne, które należy rozpocząć co najmniej 7-14 dni przed zabiegiem. Najpowszechniej stosowane leki to78:

  • Fenoksybenzamina – zazwyczaj w dawce początkowej około 10 mg 2-3 razy dziennie9
  • Doksazosyna – alternatywna opcja, z mniejszą liczbą działań niepożądanych10
  • Prazosyna – również stosowana jako alternatywa11

Po ustabilizowaniu blokady alfa-adrenergicznej można rozważyć wprowadzenie beta-blokerów (np. propranololu). Istotne jest, aby nigdy nie stosować beta-blokerów przed odpowiednią blokadą alfa, ponieważ może to prowadzić do kryzysu nadciśnieniowego1213.

Fenoksybenzamina jest bezpieczna do stosowania w ciąży, podczas gdy beta-blokery powinny być wprowadzane tylko w razie konieczności, gdyż ich stosowanie wiąże się z ograniczeniem wzrostu wewnątrzmacicznego14.

Leczenie chirurgiczne paraganglioma

Chirurgiczne usunięcie guza pozostaje podstawową i jedyną potencjalnie leczniczą metodą leczenia paraganglioma1516.

Rodzaje zabiegów chirurgicznych

Wybór techniki chirurgicznej zależy od lokalizacji guza, jego wielkości oraz doświadczenia zespołu operacyjnego17:

  • Laparoskopowa adrenalektomia – zalecana dla guzów nadnerczy o wielkości do 6 cm1819
  • Otwarta adrenalektomia – rekomendowana dla guzów nadnerczy powyżej 6 cm, aby zapewnić pełne usunięcie guza, zapobiec pęknięciu guza i lokalnym nawrotom20
  • Operacje otwarte – zalecane w przypadku paraganglioma pozanadnerczowych, które mają wyższe ryzyko złośliwości i często są zlokalizowane w trudnych anatomicznie regionach21

Podczas operacji chirurg sprawdza okoliczne tkanki i węzły chłonne w celu oceny, czy guz się rozprzestrzenił. Jeżeli tak, te tkanki również mogą zostać usunięte2223.

Leczenie chirurgiczne w chorobie przerzutowej

Nawet w przypadku choroby przerzutowej, chirurgiczne usunięcie guza pierwotnego jest zalecane, jeśli jest to wykonalne. Takie podejście pomaga złagodzić objawy sercowo-naczyniowe i inne związane z nadmiernym wydzielaniem katecholamin lub uciskiem guza na sąsiednie narządy. Ponadto zmniejsza masę docelową dla terapii radiofarmaceutycznej24.

W badaniu porównującym skuteczność chirurgii laparoskopowej i otwartej w leczeniu przerzutowych paraganglioma, zabieg laparoskopowy wykazał wyższy wskaźnik wyleczenia (44,4%) w porównaniu do operacji otwartej (29,3%)25.

Operacja oszczędzająca korę nadnerczy

W przypadku dziedzicznych form paraganglioma można rozważyć operację oszczędzającą korę nadnerczy, aby uniknąć dożywotniej terapii hormonalnej i zaburzeń związanych z utratą hormonów nadnerczowych. Jednak w przypadku mutacji SDHB, ze względu na zwiększone ryzyko nawrotu miejscowego i/lub przerzutów, nie zaleca się operacji oszczędzającej korę nadnerczy2627.

Embolizacja przedoperacyjna

W niektórych przypadkach, szczególnie dla dużych guzów, można rozważyć embolizację przedoperacyjną w celu zmniejszenia ryzyka krwawienia śródoperacyjnego. Procedura ta pozostaje jednak kontrowersyjna28.

Nowy przegląd literatury wskazuje, że u pacjentów poddanych embolizacji przedoperacyjnej utrata krwi podczas operacji była znacząco mniejsza, a czas operacji krótszy niż u tych, którzy nie przeszli tej procedury. Embolizacja przeprowadzona mniej niż 48 godzin przed operacją może znacząco zmniejszyć utratę krwi, czas operacji i długość pobytu w szpitalu29.

Radioterapia w leczeniu paraganglioma

Radioterapia wykorzystuje wysokoenergetyczne promienie (np. promieniowanie rentgenowskie, protonowe) do kontroli wzrostu guza lub zniszczenia komórek nowotworowych30.

Wskazania do radioterapii

Radioterapia jest zalecana w następujących sytuacjach3132:

  • Gdy paraganglioma nie może być całkowicie usunięty operacyjnie
  • W celu łagodzenia bólu spowodowanego przerzutami
  • W przypadku małych, niewydzielających hormonów, łagodnych guzów podstawy czaszki i szyi, gdy usunięcie wiązałoby się z uszkodzeniem krytycznych struktur naczyniowych lub nerwowych
  • W przypadku nawrotów po resekcji chirurgicznej

Rodzaje radioterapii

Dostępne są różne techniki radioterapii3334:

  • Frakcjonowana radioterapia stereotaktyczna (FSRT) – może być skuteczną i bezpieczną alternatywą dla operacji chirurgicznej, szczególnie w zachowaniu funkcji nerwu twarzowego
  • Cyberknife – system robotyczny dostarczający precyzyjne impulsy wysokiej dawki promieniowania do tkanki docelowej, ograniczając ekspozycję otaczających zdrowych tkanek35
  • Gamma Knife i radioterapia stereotaktyczna oparta na akceleratorze liniowym (LINAC) – używane do precyzyjnej radioterapii guzów36

Badania wykazały, że radioterapia prowadzona przy użyciu techniki IMRT (modulacja intensywności wiązki) może osiągnąć kontrolę lokalną porównywalną z chirurgią, przy mniejszym ryzyku zachorowalności37.

Terapie radioizotopowe w leczeniu paraganglioma

Terapie radioizotopowe stają się coraz ważniejszą opcją w leczeniu paraganglioma, szczególnie w przypadku choroby przerzutowej38.

Terapia 131I-MIBG

Metajodobenzyloguanidyna znakowana jodem-131 (MIBG) jest radiofarmaceutykiem, który po wstrzyknięciu do krwiobiegu pacjenta podróżuje do i wiąże się z guzem, dostarczając wysoką dawkę promieniowania bezpośrednio do komórek nowotworowych39.

Terapia MIBG jest najlepiej zbadaną i ustaloną terapią dla przerzutowych paraganglioma. Jest preferowana dla wolno rosnących guzów wykazujących akumulację MIBG w badaniach obrazowych40.

W meta-analizie 17 badań z udziałem 243 pacjentów z paraganglioma poddanych terapii MIBG, całkowitą odpowiedź uzyskano u 3% pacjentów, częściową odpowiedź u 27%, a stabilną chorobę u 52% pacjentów. U 40% pacjentów wystąpiła częściowa odpowiedź hormonalna41.

FDA w USA zatwierdziło HSA [131I]MIBG (Ultratrace, Azedra) do leczenia pacjentów w wieku od 12 lat z rozpoznaniem miejscowego, zaawansowanego lub przerzutowego paraganglioma4243.

PRRT (Peptide Receptor Radionuclide Therapy)

PRRT to radiofarmaceutyk, który po wstrzyknięciu do krwiobiegu pacjenta podróżuje do i wiąże się z guzem, dostarczając wysoką dawkę promieniowania bezpośrednio do komórek nowotworowych44.

Większość paraganglioma silnie wyraża receptor somatostatynowy podtypu 2 (SSTR2), co czyni je potencjalnymi kandydatami do PRRT z użyciem znakowanych radioizotopami analogów somatostatyny45.

W jednym badaniu porównawczym, odsetek pacjentów z guzami wykazującymi stabilizację choroby był znacząco większy po PRRT z użyciem [177Lu]Lu-DOTATATE w porównaniu do [131I]MIBG, z dłuższym czasem przeżycia wolnego od progresji/całkowitego przeżycia wynoszącym 38,5/60,8 miesięcy w grupie [177Lu]Lu-DOTATATE versus 20,6/41,2 miesięcy w grupie [131I]MIBG46.

Chemioterapia w leczeniu paraganglioma

Chemioterapia jest standardową terapią dla przerzutowych paraganglioma47.

Wskazania do chemioterapii

Chemioterapia powinna być rozważona jako leczenie pierwszej linii u pacjentów, którzy nie wykazują znacznego wychwytu radioizotopów lub z wyraźną szybką progresją choroby, związaną z dużą masą guza, lub z ciężkimi niekontrolowanymi objawami spowodowanymi wydzielaniem katecholamin lub efektem masy48.

Jeśli paraganglioma wytwarza nadmiar hormonów, przed rozpoczęciem chemioterapii pacjent otrzymuje leki kontrolujące poziom hormonów49.

Schematy chemioterapii

Najczęściej stosowanym schematem chemioterapii jest połączenie cisplatyny, winblastyny i dakarbazyny, które może być preferowane w przypadku szybko postępującej choroby50.

Inne schematy obejmują gemcytabinę i docetaksel lub różne kombinacje winkrystyny, cyklofosfamidu, doksorubicyny i dakarbazyny51.

Chociaż chemioterapia nie wykazała poprawy przeżycia u pacjentów z przerzutowym paraganglioma, może być przydatna do łagodzenia objawów52.

Terapie celowane w leczeniu paraganglioma

Terapie celowane wykorzystują leki atakujące specyficzne zaburzenia obecne w komórkach nowotworowych. Poprzez blokowanie tych substancji, terapie celowane mogą powodować śmierć komórek nowotworowych53.

Inhibitory kinazy tyrozynowej

W przypadku progresji po chemioterapii lub terapii radioizotopowej, lub jeśli chemioterapia lub terapia radioizotopowa nie są możliwe/tolerowane przez pacjenta, można rozważyć inhibitory kinazy tyrozynowej (TKI), takie jak sunitynib lub kabozantynib, szczególnie dla nosicieli mutacji RET i SDHx54.

Sorafenib, multikinazowy inhibitor, jest stosowany w leczeniu zaawansowanego raka nerki i raka wątrobowokomórkowego. Jest inhibitorem kinazy RAF, c-KIT, FLT-3, RET, VEGFR (VEGFR-2, VEGFR-3) i PDGFR (PDGFR-β). Zmniejsza aktywację MEK i kinazy MAP oraz powoduje hamowanie proliferacji komórek, inwazji, migracji i wzrostu guza55.

W jednym przypadku pacjent uzyskał korzyści kliniczne i laboratoryjne z sorafenibu, wykazując prawdziwą całkowitą odpowiedź po trzymiesięcznej terapii56.

Analogi somatostatyny

Somatostatyna jest naturalnie występującym hormonem, który działa poprzez wiązanie się z receptorem somatostatyny (SSTR), receptorem, który jest nadmiernie wyrażany w paraganglioma. Analogi somatostatyny (SSA), takie jak oktreotyd i lanreotyd, działają poprzez aktywację SSTR, co może spowolnić wzrost guza57.

Lanreotyd, analog somatostatyny, jest obecnie stosowany w leczeniu guzów neuroendokrynnych żołądkowo-jelitowo-trzustkowych, ale jego rola w leczeniu paraganglioma jest nadal niejasna. Jeden przypadek pokazuje nadzwyczajną odpowiedź przerzutowego paraganglioma na lanreotyd, co budzi zainteresowanie tą potencjalną bronią terapeutyczną58.

Terapie ablacyjne w leczeniu paraganglioma

Terapie ablacyjne wykorzystują ciepło lub zimno do zabijania komórek nowotworowych i kontrolowania wzrostu paraganglioma59.

Rodzaje terapii ablacyjnych

Dostępne są różne techniki ablacji60:

  • Ablacja radiofrekcencyjna (RFA) – używa ciepła generowanego przez fale radiowe do niszczenia guza
  • Krioablacja – wykorzystuje ekstremalne zimno do zabijania komórek nowotworowych
  • Wstrzyknięcie etanolu przezskórne (PEI) – polega na wstrzyknięciu etanolu do guza

Terapie ablacyjne mogą być rozważane w leczeniu przerzutowego paraganglioma, szczególnie w przypadku choroby oligometastatycznej (z ograniczoną liczbą przerzutów)61.

Embolizacja terapeutyczna

Embolizacja terapeutyczna jest leczeniem polegającym na blokowaniu tętnicy prowadzącej do guza. Blokowanie przepływu krwi do gruczołów nadnerczy pomaga zabić komórki nowotworowe rosnące tam62.

W Mount Sinai stosuje się embolizację do leczenia paraganglioma. Ta nowoczesna technika może zmniejszyć guz i zredukować krwawienie, co znacznie ułatwia jego chirurgiczne usunięcie63.

Obserwacja (watchful waiting)

W niektórych przypadkach lekarze mogą zalecić przeciwko natychmiastowemu rozpoczęciu leczenia paraganglioma. Zamiast tego mogą preferować ścisłe monitorowanie stanu pacjenta podczas regularnych wizyt kontrolnych. Jest to znane jako „watchful waiting” (czujne oczekiwanie)64.

Ta strategia może być opcją, jeśli paraganglioma rośnie powoli i nie powoduje objawów6566.

Czujne oczekiwanie z częstymi wizytami kontrolnymi może być optymalnym początkowym podejściem u pacjentów z niefunkcjonującym paraganglioma głowy i szyi, szczególnie bez dowodów na znaczący wzrost guza i/lub ucisk otaczających struktur67.

Badania kliniczne w leczeniu paraganglioma

Badania kliniczne to badania nowych metod leczenia lub nowych sposobów wykorzystania starszych metod leczenia. Jeśli jesteś zainteresowany badaniami klinicznymi dla paraganglioma, porozmawiaj ze swoim lekarzem o dostępnych opcjach68.

Obecnie badane są nowe rodzaje leczenia w badaniach klinicznych. Te nowe metody obejmują69:

  • Inhibitory PI3K w połączeniu z inhibitorami mTORC1
  • Inhibitory HIF-2α
  • Inhibitory PARP
  • Analogi SSTR2
  • Inhibitory HDAC
  • Czynniki demetylujące DNA
  • Immunoterapię

Dla dzieci z paraganglioma, badania kliniczne mogą obejmować70:

  • Badanie kliniczne sprawdzające próbkę guza pacjenta pod kątem określonych zmian genowych
  • Badanie kliniczne terapii 131I-MIBG
  • Badanie kliniczne nowego leku chemioterapeutycznego (guadecytabina)

Terapia paraganglioma w ciąży

Leczenie paraganglioma podczas ciąży może obejmować operację całkowitego usunięcia nowotworu71.

Resekcja guza często może być bezpiecznie przeprowadzona podczas drugiego trymestru, lub resekcja guza może być połączona z cesarskim cięciem w przypadku pacjentek zdiagnozowanych później w ciąży72.

Leczenie paliatywne

W przypadku zaawansowanej choroby, leczenie paliatywne ma na celu łagodzenie objawów i poprawę jakości życia73.

Opcje leczenia paliatywnego mogą obejmować74:

  • Chirurgię w celu usunięcia jak największej ilości nowotworu
  • Chemioterapię kombinowaną
  • Radioterapię z 131I-MIBG
  • Zewnętrzną radioterapię w miejscach (takich jak kości), gdzie nowotwór się rozprzestrzenił i nie może być usunięty chirurgicznie
  • Embolizację
  • Terapię ablacyjną

Obserwacja po leczeniu paraganglioma

Po leczeniu paraganglioma konieczna jest dalsza obserwacja75.

Po operacji krew lub mocz są badane w celu sprawdzenia, czy poziomy metanefryny, a następnie katecholamin powróciły do normy. Prawidłowe poziomy metanefryny są oznaką, że wszystkie komórki paraganglioma zostały usunięte, jeśli guz wydzielał katecholaminy76.

Wszystkim pacjentom z paraganglioma, którzy zostali poddani leczeniu chirurgicznemu, zaleca się obserwację przez co najmniej 10 lat w celu wykrycia nawracającej choroby i tworzenia nowych guzów77.

Dożywotnia obserwacja jest zalecana u pacjentów z paraganglioma wysokiego ryzyka (mutacja linii zarodkowej, młody wiek (20 lat), duży guz (≥6 cm), nosiciele SDHB) oraz u wszystkich pacjentów z paraganglioma78.

Personalizacja leczenia paraganglioma

Wybór leczenia pierwszej linii i kolejnych podejść terapeutycznych zależy od charakterystyki pacjenta, objawów klinicznych, typu guza, awidności guza dla radioizotopów, obciążenia chorobą (ograniczone/rozległe) oraz jej agresywności (ograniczona stabilna choroba, rozległa choroba z wolną/szybką progresją) i dostępnych zasobów79.

Wielodyscyplinarne podejście przez doświadczony zespół medyczny jest konieczne w celu określenia najbardziej odpowiedniego, spersonalizowanego planu leczenia opartego zarówno na charakterystyce pacjenta (wiek, stan zdrowia), jak i cechach guza (lokalizacja, wielkość, zasięg, profil biochemiczny, obrazowanie funkcjonalne, a ewentualnie tło genetyczne), ważąc zalety i wady każdej opcji80.

W celu jeszcze bardziej spersonalizowanego leczenia i poprawy rokowania tej molekularnie złożonej choroby, bezsprzecznie badania genetyczne w kierunku mutacji linii zarodkowej, a także profilowanie genomowe w kierunku mutacji somatycznych, tam gdzie są dostępne, muszą być udoskonalone i stać się standardową praktyką81.

    Most often, paraganglioma treatment involves surgery to remove the tumor. If the tumor makes hormones, healthcare professionals often use medicines to block the hormones first. If the paraganglioma can’t be removed with surgery or if it spreads, you may need other treatments. […] Your treatment options for paraganglioma depend on various factors. These include: Where the tumor is located. Whether it is cancerous and has spread to other parts of the body. Whether it makes extra hormones that cause symptoms. […] Treatment options include: […] If your paraganglioma makes extra catecholamines, you’ll likely need treatments to block the effects or lower the levels of these hormones. These treatments lower high blood pressure and control other symptoms. It’s important for blood pressure and symptoms to be under control before other paraganglioma treatment starts. That’s because treatment can cause the tumor to release very large amounts of catecholamines and that can lead to serious problems.

Medications may include: […] Treatment options for paraganglioma include: […] Surgery is the main form of treatment for paragangliomas. During the surgery to remove the tumor, your surgeon will check the surrounding tissue and lymph nodes to see if the tumor has spread. […] Radiation therapy is a cancer treatment that focuses strong beams of energy to destroy cancer cells or keep them from growing while sparing as much surrounding healthy tissue as possible. […] Chemotherapy is the standard therapy for treating metastatic paraganglioma.

    https://pheopara.org/education/paraganglioma
    Paragangliomas, if detected early, can be successfully treated and managed in the vast majority of cases. If possible, the treatment of choice for the condition is surgery to remove the tumor(s), but there are other treatment options. Surgical treatment usually alleviates symptoms. Once diagnosed, it is recommended to be seen by a multi-disciplinary medical team with pheo para experience. […] When surgery is not an option due to multiple tumor sites, metastatic disease, or the location of the paraganglioma, chemotherapy, radiation or radiopharmaceutical therapy are also treatment options. […] Surgery to remove a paraganglioma is the preferred treatment option. During surgery, the tissue and lymph nodes close to the tumor may be checked and if the tumor has spread, these tissues may also be removed. Drugs may be given before, during, and after surgery to keep blood pressure and heart rate normal.

    Pheochromocytomas (PCC) and paragangliomas (PGL) are rare neuroendocrine tumors arising from chromaffin cells in the adrenal medulla, sympathetic or parasympathetic ganglia. Currently, the only curative treatment option of pheochromocytomas/paraganglioma (PPGL) is surgical resection. Surgery aims to eliminate both risks of hypersecretion and tumor growth. The consequences of hypersecretion should be carefully controlled with medical therapy before and during the surgery. […] Therefore, all patients with PPGL who are surgically treated should be followed for at least 10 years for recurrent disease and new tumor formation. […] Although surgical resection is the only curative treatment for PPGLs, surgical treatment is palliative except for resectable locoregional metastases in metastatic disease or for isolated distant metastases. The purpose of palliative treatment is to reduce hormone secretion and prevent metastasis-related complications in a critical anatomical location.

    Radiation therapy is reserved for patients with small, non-secretory, benign tumors in the skull base and neck when removal would involve damage to critical vascular or nerve structures. It is also considered appropriate for patients with jugular paragangliomas and more advanced tympanic paragangliomas unless they are symptomatic from catecholamine secretion or tumor bulk. Radiation therapy is also helpful with recurrent tumors after surgical resection. […] Preoperative preparation is necessary to prevent hypertensive crisis, malignant arrhythmias, and multiorgan failure intraoperatively. Clinicians typically initiate antihypertensive medications at least 7 days before surgery to achieve low-normal blood pressure, especially in patients with catecholamine-secreting tumors. […] Patients experiencing recurrent disease after surgical resection may consider radiotherapy or repeat resection. A retrospective review of recurrent head and neck paragangliomas treated with radiotherapy or surgery demonstrated 5-year freedom from 100% and 62% progression, respectively.

    Pheochromocytomas (PCC) and paragangliomas (PGL) are rare neuroendocrine tumors arising from chromaffin cells in the adrenal medulla, sympathetic or parasympathetic ganglia. Currently, the only curative treatment option of pheochromocytomas/paraganglioma (PPGL) is surgical resection. Surgery aims to eliminate both risks of hypersecretion and tumor growth. The consequences of hypersecretion should be carefully controlled with medical therapy before and during the surgery. […] Therefore, all patients with PPGL who are surgically treated should be followed for at least 10 years for recurrent disease and new tumor formation. […] Although surgical resection is the only curative treatment for PPGLs, surgical treatment is palliative except for resectable locoregional metastases in metastatic disease or for isolated distant metastases. The purpose of palliative treatment is to reduce hormone secretion and prevent metastasis-related complications in a critical anatomical location.

    Pheochromocytoma Treatment (and PPGL) […] The only treatment for a pheochromocytoma or paraganglioma is surgery to remove your adrenal gland (which includes your adrenal nodule), which should be performed by a specialized adrenal, endocrine surgeon. […] For a pheochromocytoma, this involves an adrenalectomy, usually done via a minimally invasive, laparoscopic approach. However, if there is concern for, or a diagnosis of cancer, an open adrenalectomy may be performed. For patients with certain genetic mutations, occasionally a partial adrenalectomy may be offered. […] The majority of paragangliomas are removed with open surgery, though occasionally a minimally invasive laparoscopic technique can be used.

Currently, the only curative treatment option of pheochromocytomas/paraganglioma (PPGL) is surgical resection. Surgery aims to eliminate both risks of hypersecretion and tumor growth. The consequences of hypersecretion should be carefully controlled with medical therapy before and during the surgery. […] Therefore, all patients with PPGL who are surgically treated should be followed for at least 10 years for recurrent disease and new tumor formation.

[…] Since all patients with PPGL have a risk of recurrence, they should be followed up after R0 resection. […] Lifelong follow-up is recommended for high-risk PCC patients (germline mutation, young age (20 years), large tumor (56 cm), SDHB carriers) and all PGL patients.

    The choice of the first line treatment and of subsequent therapy approaches depends on the patients’ characteristics, clinical symptoms, tumor type, radioisotope tumor avidity, disease burden (limited/extensive) as well as its aggressivity (limited stable disease, extensive disease with slow/rapid progression) and available resources. […] A multidisciplinary approach by an expert medical team is needed in order to define the most proper, personalized treatment plan based on both patient characteristics (age, health status) and tumour features (location, size, extent, biochemical profile, functional imaging and eventually genetic background), weighing the pros and cons of each option.

    Pheochromocytomas (PCCs) and Paragangliomas (PGLs), commonly known as PPGLs to include both entities, are rare neuroendocrine tumors that may arise in the context of hereditary syndromes or be sporadic. However, even among sporadic PPGLs, identifiable somatic alterations in at least one of the known susceptibility genes can be detected. Therefore, about 3/4 of all PPGL patients can be assigned to one of the three molecular clusters that have been identified in the last years with difference in the underlying pathogenetic mechanisms, biochemical phenotype, metastatic potential, and prognosis. While surgery represents the mainstay of treatment for localized PPGLs, several therapeutic options are available in advanced and/or metastatic setting. However, only few of them hinge upon prospective data and a cluster-oriented approach has not yet been established. In order to render management even more personalized and improve the prognosis of this molecularly complex disease, it is undoubtable that genetic testing for germline mutations as well as genome profiling for somatic mutations, where available, must be improved and become standard practice. This review summarizes the current evidence regarding diagnosis and treatment of PPGLs, supporting the need of a more cluster-specific approach in clinical practice.
